Hey guys....I need to figure out if the OPUS can handle my current system:
Athlon XP 1800 (OC'ed)
ATI Radeon 8500
3.5" 60gb hdd
PCI Wireless Card
PCI TV Card
a few USB devices (EL keyboard, seperately powered USB hub, Bluetooth dongle)
My other option is to go with an inverter, but I would really like to go with an Opus to cut down on the # of devices. Let me know if this will be fine.
I really doubt even an Opus 150W could handle all that....though a more powerful version is imminent.
You'll have to use a power calculator, but your only chance is to underclock and undervolt the processor, replace the video card with something less power hungry and remove a PCI card. Perhaps use onboard audio instead of the soundblaster? USB 802.11 instead of PCI?
Another option is to use more than one Opus (one feeding just the mainboard, processor & PCI cards) and one running the Hard drives, fans etc.) or a beefier alternative. Do a search for 'sproggy' and check out the following thread:
